SONPANEL L/L is a variant of the X/L and as the name implies two Rugran cores make up the acoustic insulation value.
The thermal characteristics are identical to those of the X/L panel.
SONOPANEL L/L consists of two different sound proofing mats comprised of two rubber/PU mats with a density of 650 kg/mÑ. The special multiple construction of SONOPANEL L/L not only ensures high insulation value but also great thermal insulation. This last aspect is due to the use of our Stypir 60 as the core of the panel.
SONOPANEL L/L panels ensure excellent sound proofing and thermal insulation.
Panels are available in both standard thicknesses as well as a special structure.
Our soundproofing sandwich panels are utilised in motor and sail yachts, city, and intercity busses, coaches, houses, offices, theatres and sound proofed housings.
